Abstract

The invention belongs to the technical field of building construction, particularly relates to a pipe clamp and a grouting method applicable to double-U-shaped buried pipes of a ground source heat pump system and solves the technical problem that the design of the prior art is not reasonable and the like. The pipe clamp comprises a pipe clamp body, wherein four position limiting holes capable of maintaining the mutual space of the double-U-shaped buried pipes are arranged on the pipe clamp body, the center of the pipe clamp body is provided with a grouting hole used for being connected with a grouting mechanism. The grouting method applicable to the double-U-shaped buried pipes of the ground source heat pump system comprises the following steps of A, pipe placing: the grouting mechanism is connected into the grouting hole arranged in the center of the pipe clamp body, and then, the double-U-shaped buried pipes and the pipe clamp body are inserted into ground buried holes; and B, grouting: the grouting mechanism pulls the pipe clamp body, so the pipe clamp body 1 ascends in the axial direction of the double-U-shaped buried pipes in the grouting process. Compared with the prior art, the pipe clamp and the grouting method have the advantages that the mutual space of the double-U-shaped buried pipes is maintained, the short circuit of the double-U-shaped buried pipes cannot easily occur, the blockage cannot easily occur, and the slurry filling intensity is high.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and relates to the buried pipe construction of a ground source heat pump system, in particular to a pipe clamp and a grouting method suitable for a double U-shaped buried pipe of a ground source heat pump system. Background technique [0002] In the double U-shaped ground source project, due to the deep depth of the buried hole, the position and spacing of the heat pipes in the buried hole cannot be well controlled within the design range, which makes it difficult for the heat exchange effect to meet the design requirements. The heat transfer effect of the heat pipe directly determines the operating effect of the ground source heat pump system. The heat transfer pipe directly exchanges heat with the ground source side. The heat pipe backfilling slurry generally has two methods: manual backfilling and mechanical backfilling; manual backfilling is generally backfilling the slurry from the ...

AI Technical Summary

Problems solved by technology

The heat transfer pipe directly exchanges heat with the ground source side. There are generally two methods of backfilling the heat transfer pipe with manual backfilling and mechanical backfilling; among them, manual backfilling is generally backfilling the slurry from the upper part, and this filling method often leads to poor filling density of the slurry. ;Mechanical backfilling requires special feeding pipes and mud pumps to backfill from the bottom, which is difficult to construct and the filling density of the slurry is not ideal

However, in the existing technology, generally, several special pipe clips are used to fasten the heat pipes together first, and then inserted into the buried hole. The disadvantage of this method is that when the backfill slurry is close to the special pipe clips, due The special tube clamp will block the slurry, and there will be poor filling density of the slurry, and it is difficult to install the tube. Because the filling effect cannot be observed under the buried hole, sometimes it will be blocked, and a tube interval short circuit will be formed between the heat transfer tubes, which directly affects Operation effect of buried pipe ground source heat pump system

[0004] The above scheme improves the existing technology to a certain extent by placing mechanical backfill pipes in the middle circular hole for backfilling, but due to the deep buried holes, the distance and position between the heat pipes cannot use this ground source. Heat pump system vertical heat exchanger tube stuck is completely solved

In addition, the pipe clips in the above scheme are still fixed pipe clips, that is, the pipe clips are fixed on the buried pipe, the construction cost is high, and the phenomenon of blockage and short circuit between pipe intervals still exists, and the filling density of the slurry is poor, which directly affects the buried pipe.
